Abstract: Multicommunication is a prevalent behavior found in online human conversation, and yet most human-to-chatbot approaches do not address it. Intrinsic parts of human-to-human conversations like the flexibility of communication tempo, the compartmentalization of conversation, and the topics and intensity of interactions are elevated in multicommunicative human-to-chatbot conversations. Previous Deep Learning approaches may overlook these intrinsic characteristics due to them focusing on the evaluation of human-likeness through sensible and specific responses [Google’s Meena] or on-topic responses [Amazon’s Alexa Prize Challenge]. In order to both capture the human-likeness of sensible, specific, and on-topic responses, we use the fundamental unit of conversation as defined by Conversational Analysis: the adjacency pair; and expand it into an Adjacency Relation to describe a succession of adjacency pairs. To illustrate this Conversational Analysis and Multicommunication Theory, we are developing an Interactive Behavior Tree Conversation Management Framework for Multicommunicating in an Open-Domain, Retrieval-Based Chatbot. We will describe a preliminary deployment of this framework and highlight its advantages (and limitations). We show that this framework provides additional human-likeness not provided by other response retrieval techniques and show this using our own Multi-Engagement Metric. Furthermore, we describe a real problem where a solution of this type will be applied and studied.
